| 摘 要： | 本文对OFDM体制下DRM系统中基于导频辅助调制(PSAM)的信道估计器进行了分析,描述了数字调幅广播中导频单元的分布,在DRM系统基础上分别结合最小平方准则(LS)和线性最小均方误差准则(LMMSE),提出了信道估计方法,并在Matlab环境下,使用Watterson信道模型进行了蒙特卡罗模拟,给出了性能比较.

| Abstract: | Based on PSAM in DRM system, the OFDM channel estimators are analyzed, and the distribution of pilot references in DRM system is described in this paper. A channel estimation method related to DRM system is proposed by combining LS (least square) and LMMSE (linear minimum mean-squared error) rules. A Monte Carlo simulation is implemented by using Watterson channel model in Matlab system, and the comparison on performance is presented. |
